Capillary electrochromatography of steroids

Separation of peptides by strong cation-exchange capillary electrochromatography

“…The chromatofocusing has already been used responsible for the high column efficiency. It was [30,31], but the CE stacking has not been used obvious that CE stacking was effective only for the intentionally to improve the detection in CEC to our solutes in solution. Most of the solutes in the sample knowledge.…”

Capillary electrochromatography for pesticide analysis: Effects of environmental matrices

“…To date, little attention has been given to the suitability of CEC columns for the analysis of complex matrices. It has been shown that steroids can be analyzed in extracts derived from human plasma [14]. In another example of steroids in equine urine and plasma, peak broadening was observed [15].…”

Centrifuge microextraction coupled with sweeping–MEKC to analyze trace steroid hormones in urine samples

“…Traditional sample preparations, such as liquid-liquid extraction (LLE) and solid-phase extraction (SPE), have been used for sample cleanup and/analyte enrichment in the determination of steroid hormones [23][24][25][26]. However, these methods are tedious, time-consuming, and use relatively large amounts of sample and organic solvent.…”
